Setting up throttle with BeaxtX (Gaui nx4)

       Remove this ad - become a site supporter!
I'm in the middle of setting up my first nitro heli and have some questions about the throttle channel.
So I know with the AR7200BX you're not suppose to use trim, but I've seen a lot of guys when setting up throttle the put the trim up to run at idle and then to kill the engine you'd bring the throttle trim all the way down.
Does beastX work properly when using trim on the throttle channel?

Also when I am setting my end points so the throttle servo isn't mashing the engine throttle arm to the end (with beaxtX) do I use end point adjustment or do I set my throttle curve to adjust endpoints?

(Gaui Nx4, with the os36 engine, gaui gov, AR7200BX)

Any tips with the throttle on top of my two questions after welcome.
Thanks guys

Re: Setting up throttle with BeaxtX (Gaui nx4)

are you digital trim or analoge, either way make sure your mechanical set up is perfect, ie throttle arm and your servo arm are identical from center to the ball and have your throttle linkage the same lenght as the centre of servo shaft to the centre of your throttle shaft.
now you may have to try a few servo arm to see which one will give you the perfect 90 degrees between servo arm and throttle arm whith your linkage installed (keep throttle arm lose) a little sub trim should be ok but try for none and all end points at 100.
now on your throttle barrel there are some marks on the carb and one on the barrel, the carb 1 is for closed the centre is half and full throttle but right close to the closed mark is the one for idle, with all throttle trim on your radio at 0 put the barrel to the idle postion and tighten the arm and check for range of movement, centre stick on your radio you should be 50% at the carb and the same at full throttle,you may have to change end points a bit. but make sure your mechanical set up perfect and your linkage length is the same centre to centre as your servo and throttle.
I have a 600 and 700 and the throttles on both are perfect 0 sub trim and minimal end point ajustment, 3to4% just to stop servo noise they are bang on, took some and alot of servo arms to find the perfect ones, take your time do your best and if you have any questions give me a pm.
